Estradiol Reduces Incorporation of Radioactive Sulfate into Cartilage and Aortas of Rats

Inhibition of Synthesis of Sulfated Mucopolysaccharides by Estradiol

The influence of estradiol upon incorporation of isotopes into the sulfated acid mucopolysaccharides of connective tissues of the rat has been studied. Administration of the hormone for 3 weeks significantly reduces the in vitro incorporation of S(35)-sulfate into cartilage and thoracic aorta without significantly altering the amount of hydrolyzable sulfate in these tissues. The reduction of su...

Metabolic Effects of Lathyrogenic Agents on Cartilage in Vivo and in Vitro

The effects of lathyrogenic agents in vivo and in vitro are described, in respect to some biochemical indices of cartilage metabolism. Lathyrogenic agents in vivo inhibited the incorporation of radiosulfate into rat epiphyseal cartilage and the isolated chondroitin sulfate. No significant changes in hydroxyproline or hexosamine content of epiphyseal cartilage were found, but there was a marked ...

Vitamin D3 Induces Gene Expression of Ox-LDL Scavenger Receptors in Streptozotocin-Induced Diabetic Rat Aortas: New Insight into the Role of Vitamin D in Diabetic Atherosclerosis

Background: Several lines of evidence suggest that oxidized LDL (Ox-LDL) scavenger receptors play a crucial role in the genesis and progression of diabetic atherosclerosis. This study aimed to elucidate the effect of vitamin D3 on gene expression of lectin-like oxidized LDL receptor-1 (LOX-1), scavenger receptor-A (SR-A), Cluster of Differentiation 36 (CD36), and Cluster of Differentiation 68 (...

اثر متفورمین بر لانه گزینی و وقوع حاملگی در پی بر انگیختن سندرم تخمدان پلی کیستیک در موش صحرایی

Background: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. Metformin which is effectively used for the treatment of anovulatory PCOS improves pregnancy rate and endometrial receptivity and reduces the risk of miscarriage. The aim of this study was to evaluate the effects of metformin on the endometrium, the number of fetuses and hormonal levels ...
